Same here, and this is just to note that the reason the very first
example in docvariations.tex

$$\begin{variations} x & \mI & & & 0 & & & \pI \\ \filet \m{\frc{1}{x}} & \h0 & \d & \mI & \bb & \h\pI & \d & 0 \\ \end{variations}$$

does not work is \frc. If replaced with \frac, it does. So, it would
seem that docvariations.tex might have to be taken with caution.
